Brevo + MarketingAtelier: connect your account or migrate

Two approaches to choose from: keep Brevo as your sending engine and run your campaigns from MarketingAtelier, or migrate fully to native sending. Here is how to do it, what syncs, and how to choose.

Updated on June 22, 2026

Already using Brevo (formerly Sendinblue) for your sends and just discovering MarketingAtelier? Good news: you don't have to migrate everything overnight. Two approaches coexist. You can connect your Brevo account and keep sending through Brevo while building and running your campaigns from MarketingAtelier, or migrate fully to native sending. This guide covers both, what syncs, and how to choose.

Approach 1: connect Brevo and keep your sending

This is the "zero disruption" option. You keep your Brevo account, your sender domain, your sending reputation and all your history. MarketingAtelier becomes the workshop where you design your emails and orchestrate your campaigns; Brevo stays the sending engine. Concretely, through SendAtelier and its ESP connector pattern:

  • Your campaign HTML is pushed to Brevo from MarketingAtelier.
  • Sending is triggered on Brevo's side, with your existing setup.
  • Personalization tokens are translated into Brevo's native syntax, which resolves the variables with its own contacts.
  • Statistics are pulled back via synchronization and surface in your MarketingAtelier dashboards.

You get the email builder, the design system and the platform's AI, without touching your sending infrastructure. Ideal if your Brevo domain is well warmed up and you don't want any deliverability risk.

Approach 2: migrate to native sending

If you want everything under a single platform, you can migrate fully. MarketingAtelier's native sending runs on a modern transactional infrastructure: you import your contacts via CSV, you verify your sending domain through DNS, and you send directly from MarketingAtelier with no external dependency. Your personalization tokens are then resolved on the platform side, one HTML per recipient.

This approach simplifies billing (a single subscription) and keeps your data — contacts, consents, statistics — in one place. It's the natural choice if Brevo only serves to send and you want to move away from it.

How to connect your Brevo account

Connecting takes just a few minutes from SendAtelier:

  • Get your API key from your Brevo account.
  • In MarketingAtelier, open SendAtelier then the sending mode (connections).
  • Pick Brevo as the connector and paste your API key.
  • Verify the connection: your Brevo lists and senders become available.
  • Build your campaign, then send a test before the broadcast.

Gotcha to know. With Brevo, the send test fails if the test address does not exist in your Brevo contacts. Add that address as a contact in Brevo first, then run the test again from MarketingAtelier. Once that detail is handled, everything goes through.

What syncs

Beyond sending, the CRM can synchronize and import your contacts from your ESP, mapping the statuses to the right consent. Here is what flows between Brevo and MarketingAtelier depending on the approach you choose:

When to choose which?

Stay on connected Brevo if…

  • Your Brevo domain is warmed up and your deliverability is excellent.
  • You want to try MarketingAtelier without touching your sending.
  • Your team has well-established processes around Brevo.

Migrate to native sending if…

  • You want a single subscription and a single interface.
  • You centralize contacts, consents and statistics in one place.
  • Brevo only serves to send and you want to move away from it.

You don't have to decide right away: many teams connect Brevo first, find their footing, then migrate once confident. To dig deeper into positioning, read our MarketingAtelier vs Brevo comparison.
